| 2.CHECK HARNESS AND CONNECTOR (MULTI-MEDIA INTERFACE ECU - RADIO RECEIVER ASSEMBLY) |
Disconnect the F55 radio receiver assembly connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| L40-11 (ACC) - F55-11 (ACC) | Always | Below 1 Ω |
| L40-12 (+B) - F55-12 (+B) | Always | Below 1 Ω |
| L40-7 (GND) - F55-7 (GND) | Always | Below 1 Ω |
| L40-11 (ACC) - Body ground | Always | 10 kΩ or higher |
| L40-12 (+B) - Body ground | Always | 10 kΩ or higher |
| L40-7 (GND) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
